1. Some residual epidermal tissue. The outer cortex has one to several rows of cells with slightly thickened walls, and sparse wall pores are visible; sclerenchymatous cells are polygonal or somewhat oblong, often thickened in bead-like chains, slightly lignified. The parenchyma cells of the stele are relatively large, subrounded or polygonal, and sometimes pits are visible. Vascular bundles are collateral or amphicribral, scattered; vessels occur in groups of two to several, non-lignified. In the parenchyma tissue, bundles of calcium oxalate raphides can be seen, some scattered; the parenchyma cells contain polysaccharide mass-like substances that appear brown or light brownish purple with iodine solution.

2. Take the powder and prepare a 10% aqueous infusion, add 2-4 drops of iodine test solution; it appears purplish red to wine red.
